获取FOSUserBundle组的用户（Symfony2）

Question

I have been struggling with this question for the past couple of hours and haven't been able to find anything.

I have configured the FOSUserBundle and have the groups activated correctly and working. However, the user-group relation is defined as follows in the User class :

/**
 * @ORM\ManyToMany(targetEntity="Netlabs\UserBundle\Entity\Group")
 * @ORM\JoinTable(name="fos_user_user_group",
 *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="group_id", referencedColumnName="id")}
 * )
 */
protected $groups;

and in the Group class, I do not even have a $user list defined. I tried loads of "normal" things like creating a $users variable in my Group class and defining it's relation to the User object, but it is not playing nice with the FOSUserBundle (every time, it creates a NEW table to create the relation, when there is already one in place). For example:

/**
 * @ORM\ManyToMany(targetEntity="Netlabs\UserBundle\Entity\Group", inversedBy="groups", cascade={"all"})
 * 
 */
protected $users;

Any suggestions ?

Again, my main goal is : I want to be able to do Group->getUsers()

Answer 1

In your Group class, your targetEntity must be User and not Group. Furthermore, try to add an inversedBy rule for the $groups attributs and modifie inversedBy in mappedBy for $users.

/**
 * @ORM\ManyToMany(targetEntity="Netlabs\UserBundle\Entity\Group", inversedBy="users")
 * @ORM\JoinTable(name="fos_user_user_group",
 *      joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="group_id", referencedColumnName="id")}
 * )
 */
protected $groups;

And

/**
 * @ORM\ManyToMany(targetEntity="Netlabs\UserBundle\Entity\User", mappedBy="groups")
 * 
 */
protected $users;
